Types

type Chunk

type Chunk struct {
	Addr uint32
	Data []byte
}

A Chunk represents a run of bytes, starting at a specific address.

type RecType

type RecType byte

const (
	TypeData RecType = 0 // Simple data
	TypeEof  RecType = 1 // End of file
	TypeELAR RecType = 4 // Extended Linear Address Record
)

type RecWidth

type RecWidth int

const (
	Width16 RecWidth = 16
	Width32 RecWidth = 32
)

type Writer

type Writer struct {
	Width   RecWidth
	UseCRLF bool // True to use \r\n as the line terminator
	// contains filtered or unexported fields
}

A Writer writes bytes at addresses to an Intel HEX formatted file.

As returned by NewWriter, a Writer writes records of 32 bytes, terminated by a newline. The exported fields can be changed to customize the details before the first call to Write.

func NewWriter

func NewWriter(w io.Writer) *Writer

func (*Writer) End

func (w *Writer) End() error

func (*Writer) Write

func (w *Writer) Write(addr uint32, data []byte) error
